BED-FRAME.

Specification of Letters Patent.

Patented Oct. 16, 1917.

Application filed March 13, 1916. Serial No. 83,803.

To all whom t may concern.'

Be it known that I, CHARLES IV. WAr.- s'rRoM, a citizen of the UnitedStates, resident of Minneapolis, county of Hennepin, State of Minnesota,have invented certain new and useful Improvements in Bed- Frames, ofwhich the following is a specification.

In the manufacture of bed frames where angle bars have been used for theends of the frame, considerable difficulty has been experienced inpreventing the vertical flange of the end rails from warping or bucklingunder the pull of the bed springs thereon.

The object of my invention is to provide a means for bracing the endrails and so distributing the strain thereon that bending or buckling ofthe flanges out of their normal plane will be avoided.

The invention consists generally in various constructions andcombinations, all.

as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a plan View, partially in section, of a portion of the bedframe embodying my invention,

Fig. 2 is a transverse sectional view of the same,

Fig. 8 is a detail, sectional view, showing the manner of mounting thebridge in the end rail of the frame.

In the drawing, 2 represents the side rails of the frame, havingcastings 3 at the ends thereof to which the vertical flange 4L of theend rail is secured. The horizontal flange 5 of this rail has holes 6therein for the connection of the coiled springs 7 of the spring fabric'8. To prevent buckling or bending of the end rail under the pull of thespring fabric thereon, I provide a truss bar 9 secured to the verticalflange of the rail, preferably at 10. A bridge 11 is interposed betweenthis truss and the flange 4f and is provided with a convex seat 12 toreceive the truss bar. A lug 13 is provided on the bridge to engage theforward edge of the flange 5 and the rear end of the bridge 1% is seatedin the angle between the anges 4 and and the strain of the truss bar,instead of being transmitted through the bridge to the vertical fiange4,*is directed into the angle between the flanges and this angle issufficiently sti to resist backward pressure without buckling orbending. I am 1. In a bed frame, the combination, with an angle bar endrail having a horizontal and a vertical flange, of a truss bar, a bridgeseated against the under surfacek of said horizontal flange and havingmeans for engaging the forward edge thereof, the .forward end of saidbridge having a seat for said truss bar and the rear end of said bridgebearing on said rail in the angle between said vertical and horizontalflange.

2. In a bed frame, the combination, with an angle bar end rail having ahorizontal and a vertical flange, of a truss bar secured at its ends tothel vertical fiange of said rail, a bridge seated against the undersurface of said horizontal flange at a point mid-way substantiallybetween the ends of said rail` and having a hook to engage the edge ofsaid horizontal flange, said bridge having a recess wherein said trussbar is seated, the outer end of said bridge being seatedvin the angleformed at the junction of said horizontal and vertical flanges, and intowhich angle the pressure of the truss bar is transmitted by said bridge.

In witness whereof, I have hereunto set my hand this 29th day ofFebruary, 1916.
